Special Issue Information

Dear Colleagues,

Wheat is the dominant crop in temperate countries being used for human food and livestock feed, counted among the ‘big three’ cereal crops with over 600 million tons being harvested annually. However, under the scenario of a growing population and shortage of arable land, higher yield and quality in wheat are urgent. The aim of this Special Issue is to introduce the key techniques of the cultivations of high yield and better quality and the agronomical and physiological mechanisms underlying high yield and quality in wheat. Studies on how to improve wheat yield and quality and the reasons higher yield and quality are obtained will facilitate wheat production. Hence, research on agricultural machinery, agronomy, physiology, soil nutrition, etc. is encouraged for publication in this Special Issue.

The formation process of starch in the grain is influenced by both genetic characteristics and environmental factors, which can affect starch quality. Waxy wheat Yangnuo1 (YN1) and non-waxy wheat Yangmai15 (YM15) were subjected to heat stress at the early, medium, and late grain-filling stages using artificial intelligence temperature control. Heat stress increased the short-chain content of amylopectin in both cultivars and decreased their amylose contents. The effect of heat stress on the wheat amylopectin structure was most pronounced 16–20 days after anthesis (DAA). The crystallinity and enthalpy of starch decreased, as did the swelling potential, solubility, and transmittance, but the retrogradation degree showed an opposite trend after heat stress. Compared with YM15, YN1 exhibited superior physical and chemical properties as well as anti-aging properties of starch and consequently had greater thermal stability under heat stress due to its higher degree of branching. The most sensitive stage to heat stress for yield was 6–10 DAA, which resulted in significant decreases in grain number and 1000-grain weight, followed by 16–20 DAA, which resulted in a significant decrease only in 1000-grain weight. Our study indicated that heat stress during the early stage of grain filling resulted in a decrease in both grain weight and yield, whereas during the middle stage of grain filling, it led to a decline in starch quality, especially in non-waxy wheat.

Physiological and Agronomic Mechanisms Involved in ‘Source–Sink’ Relationship in the High-Yield Population of Weak-Gluten Wheat

In order to provide a theoretical basis and technical approach for the construction and regulation of medium- and high-yield population cultivation practice of wheat after rice, agronomic and physiological characteristics in medium-high yielding populations were investigated by setting different basic seedlings and cutting leaves and ears with isotope tracing method in week-gluten wheat (Ningmai 29). The results showed that the medium-high yield (yield above 7500 kg/km2) group could be achieved at medium densities (150 × 104/hm2 and 225 × 104/hm2), whose populations own suitable number of spikes, higher grain number per spike and thousand-grain weight (the larger and stronger ‘sink’). Meanwhile, these two medium-high yielding populations had higher leaf area index and suitable light-transmission rate after anthesis; thus, the leaf net photosynthetic rate after anthesis was higher, and the capacity of carbon assimilates was stronger. From the 15N test, it can be seen that the relationship between individuals in the medium-high yielding population (medium-density) is more harmonious, and the plant had higher nitrogen utilization efficiency. More nitrogen is concentrated in the spike at maturity. The results of the 13C pot trials showed that the top-three functional leaves had a higher capacity for source-production, which was also the main source of post-flowering assimilates. Increasing their area to improve the ‘source–sink’ ratio would help coordinate the ‘source–sink’ relationship in the group with a stronger ‘sink’. The main technical approach is to increase the area and duration of the upper-three functional leaves after anthesis on the basis of a larger sink, thus ensuring a higher source–sink ratio and a harmonious ‘source–sink’ relationship after flowering.

One-time fertilization with controlled-released fertilizer (CRF) is a promising way for reducing labor cost, increasing nitrogen use efficiency (NUE) and alleviating environmental pollution in winter wheat (Triticum aestivum L.) cultivation. However, CRF release characteristics are related to various factors such as soil properties, temperature and precipitation, and further study is needed in developing suitable fertilizer formulas adapting to local conditions. In this study, five types of CRF were used for a one-time application in a two-year field experiment conducted at two sites with two wheat cultivars. Their effects on soil inorganic nitrogen (SIN) content, nitrogen uptake, wheat growth and grain yield were investigated. The results indicated that nitrogen supply in the CRF-60/80 treatments not only ensured the tiller differentiation at the early growth stage, but also provided adequate SIN after the jointing stage, thereby facilitating the dry matter accumulation and improving post-anthesis photosynthates accumulating in grains. When compared with conventional split fertilization, the CRF-60 and 80 treatments improved the NUE by 9.7–12.1%, and boosted farmers’ economic efficiency by 282.4–327.2 CNY ha−1. According to our research, a one-time application of CRF-60 and CRF-80 could meet the needs of the two-peak nitrogen demand of wheat in Jiangyan and Yanghzou respectively, therefore increasing NUE and having low labor costs for wheat fertilizer application.
